Petra --Calling Geo people!

[RoverChic]

Ok Geo--Boys!

I have three weeks to be proficient in Petra! :ack: Help! First it was MatLab (OK I can handle that), then it was AutoCAD 06 (so far so good), now this!


Leslie? Phil? Any advice? I basically have to be able to understand well logs (decline in production due to lack of efficiency ect).....

Damn I thought you were talking about this Petra :drool:

Frac it!

Seriously though, as I work in coal instead of oil wells, I don't use Petra.... so I have to default to textbook responses (ie, you frac a well (pressurize with fluids loaded with a support medium such as sand) to open up the strata and allow for additional recovery).

When I'm using boreholes, I'm looking at the rock type from one hole to the next, correlating seams across a proposed mine site. Instead of looking at it as such, you'll be looking at an e-log (usually electrical resistivity, but they've got some neat radioactive logging now, but nothing that I've ever worked with); the e-log gives you a rough idea of the nature of the stratum (porosity, etc.).

Have to admit, it's been a LONG time since I was in exploration geophysics..... Once I get into the office I'll pull out my old books and see if there's anything helpful there.....

Suggestion: see if someone in your office has a copy of Telford's Applied Geophysics (2nd ed. is what I have, Cambridge Press), and look up chapter 11. It's been a decade since I've even tried to remember anything about induction and SP and resistivity, or even thought about the Schlumberger bros... that chapter will help you more than any other reference I can think of off the top of my head.
